MRT-Physics

  1. RF pulse applied
  2. Slice-select gradient applied
  3. Phase-encoding gradient applied
  4. Frequency-encoding gradient applied
    1. A negative GFE is applied. The spins dephase, some faster than others.
    2. The positive GFE is applied. The spins start to rephase until they are again in phase and a signal is created - the Gradient Echo
